We'll turn to that recover I of two Americans who fought for lives after coming down with ebola back in their own homes this morning cured from that deadly virus. One of those American, Dr. Kent Brantly released and there was something they did to send a very strong message as he left and ABC's Steve osunsami there again for us this morning. Reporter: Proving there's nothing to fear each and every one of his doctors, nurses and orderlies giving him a hug good-bye. God saved my life. A direct answer to thousands and thousands of prayers. Reporter: It's a far cry from what the medical team had to wear when treating him for ebola. Dr. Brantly has recovered from the ebola virus infection and can return to his family, to his community and to his life without public health concerns. Reporter: Brantly is finally home after three weeks in the isolation wing of this Atlanta hospital where he received an experimental serum, in Africa between 60 and 90% of people sick with ebola never make it. More than 1300 have died. Do not stop praying for the people of Liberia and west Africa and for a quick end to this epidemic. Reporter: His friend, Nancy writebol, that's her helping disinfect doctors. She's ambulatory and able to care for herself. Any illness that puts you in bed for a long time you're not fast at doing anything. Reporter: On the african continent the disease can causing panic. South Africa announcing that citizens from Liberia, Sierra Leone or Guinea will no longer be allowed entry into their country and any south africans traveling to the troubled region will face health screenings when they return. Doctors say these two missionaries are now cured and if they were to return to work in Liberia, they would be immune to this strain of the virus that's causing the crisis there. David? All right, Steve osunsami, thanks so much.
